  • The company produced the terbium oxide at its White Mesa Mill in Utah, using ore mined in Florida and Georgia.
  • Both terbium and dysprosium are essential for permanent magnets used in EVs, drones, robotics, and defense systems.
  • Energy Fuels is targeting commercial output of the materials by 2027.

Energy Fuels Inc. (UUUU) came under the spotlight on Wednesday, after announcing that it has successfully produced high-purity terbium oxide domestically, a crucial breakthrough that could reduce reliance on foreign sources for critical materials.

UUUU shares jumped around 5% in pre-market trading.

The company said it produced its first kilogram of 99.9% pure terbium (Tb) oxide at its White Mesa Mill in Utah, using ore mined in Florida and Georgia. This follows the production of dysprosium oxide, a heavy rare-earth element, in August 2025. Both materials are essential for high-performance permanent magnets used in electric vehicles, drones, robotics, and defense systems.

How Does It Impact The Critical Materials Supply Chain?

What makes this development significant is that terbium and dysprosium are currently subject to export controls from China, which dominates global rare earth supply. By establishing a “mine-to-oxide” capability in the U.S., Energy Fuels is helping build a more secure and independent Western supply chain.

The company plans to scale production, targeting commercial output as early as 2027, with further expansion expected by 2029. If achieved, this could support materials needed for millions of EVs annually.

“This success proves we can process and produce high purity 'heavy' rare earth oxides economically and at scale in the U.S. North America will soon have a reliable and secure U.S. commercial source of these vital critical materials ensuring availability for high-performance magnet and defense technologies,” said Mark Chalmers, CEO of Energy Fuels.  

How Did Stocktwits Users React?

One user said the company “remains one of the most overlooked powerhouses in the U.S. critical‑minerals sector.”

Another user praised UUUU President Ross Bhapu and added that the company is well-positioned to dominate the critical minerals race.
